Hi Carlo,

if you experience, that there are no answers to your thread(s)/posting(s), you might consider to read:

Important READ THIS FIRST TO FIND QUICK SOLUTION FOR THE EXISTING ISSUE/QUESTION​

In your specific case, you provide a screenshot and would like help with investigations for a root cause of ram - overusage.
Pls. be noted, that investigations are mostly based on log - files and configuration files and we have no idea at all, how you configured your server and your services. There are thousands of possible root causes here and your lonely screenshot only informs about a temporary "fail2ban" - service high ram usage, a temporary "mysql"- service high ram usage and some temporary "apache"- service high ram usage.
There are no possible fail2ban - logs and no fail2ban - configuration file ( and possible filter - definitions ), no possible mysql - logs and no mysql - configuration file, no possible apache - logs ( not even one single domain specific log - file) and no apache - configuration file.
